Connecting cable
In order to ensure measuring accuracy, comply with the following instructions when installing
a remote version:
• Fix the cable run or route it in an armored conduit. Cable movements can falsify the
measuring signal especially in the case of low fluid conductivities.
• Route the cable well clear of electrical machines and switching elements.
• Ensure potential equalization between sensor and transmitter, if necessary.
• The maximum connecting cable length is 20 m (35.6 ft).
GSM/GPRS antenna
